Hi, over the past three weeks i have had flu like symptoms including ching body, tiredness, loss of appetite, sleep disturbance, minor cough, blocked nose, sinusitis and a feeling of lightsness in the body. most of these have gone away but for the the aching body (which is better then before) and now i feel cold all over my body and have numbness in my feet. what could this be? my mum thinks that it is the flu virus working away but part of thniks that it could be something else or anxiety.
